Answer:
C 5,5, sqrt(50)
Step-by-step explanation:
so basically a^2+b^2=c^2
and 5^2+5^2 = 50 so c is sqrt of 50
Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12
4 business class rail cars has a total capacity of 260 passengers. How many passengers can travel per rail car.
<u>Per</u> is a keyword for divide.
260 divided by 4 = 65
your answer is 65
hope this helps!
To get 75 decreased by 40% you subtract 40% from 100%.
100 - 40 = 60
So to get 60% of 75 you multiply .60 by 75.
.60 x 75 = 45
You have $45 now, but you have to decrease it by 40% again. You do the same process, so we need to multiply .60 by 45.
.60 x 45 = 27
So, the final result is $27.
Answer:
x = 2
y =7
Step-by-step explanation:
the system of linear equation will be solve using substitution method,
let
Y=3x+1.............................................. equation 1
Y=2x+3.............................................. equation 2
substitute equation 1 into equation 2
3x + 1 = 2x + 3
combine the like terms
3x+1 -2x = 3
x = 3 -1
x = 2
put the value of x=2 in either equation 1 or 2
Y=2x+3.............................................. equation 2
y = 2(2) + 3
y = 4 + 3
y = 7
